REEL.

SPECIFIGATION forming part of Letters Patent N0. 492,024, dated February21, 1893. Application filed August 5, 1892. fierial No, 442,264. (Nomodel.)

illustrated in the following specification-and the accompanyingdrawings,the novel features thereof being specified in the claimsannexed to the said specification.

In the accompanying drawings representing a hose-reel embodying myimprovements, Figure 1 is a side elevation. Fig. 2 is an end View. Fig.3 is a section through the valve on the line 3-3, Fig. 4:, showing someof the parts to the left hand of said line in elevation. Fig. 4 is alongitudinal vertical section on the line 4-4, Fig. 3,-showing the valvelever and roller in elevation. Fig. 5 represents the hub of the reel andone of the reelsegments detached.

In the accompanying drawings, A represents the reel, B, the hose woundt-hereon,and C the water supply-pipe. When the hose is unwound from thereel, the reel revolves and opens a valve by which water is admittedfrom the supply-pipe to the hose, so that the water may be thrown ontothe fire instantly. The first revolution of the reel opens the valve, sothat the hose is filled with water by the time nozzle M on the end ofthe hose has been carried a few feet from the reel. The valve isoperated by a spiral cam which revolves with the reel, being permanentlyattached thereto, so that there is nothing to be done in case of analarm of fire, except to draw the hose from the reel and open the cock ein the nozzle M. The construction is such that the valve may be closedby hand and the motion of the reel in rewinding the hose thereon doesnot affect the valve.

Q, represents a suitable base or bed-plate, on which the reelAissupported by the standards G t, in such manner that it may revolvefreely.

. The reel may be constructed in any ordinary or suitable manner, beingprovided with the spiders H H, and the slats N N, about which the hose Bis wound. I prefer however to make the spiders of the cast segmentsrepresented in Fig. 5,each segment comprising one or two spokes and aportion of the rim, and to arrange the slats N so that they may yieldinward slightly on springs or, in order to permit the expansion of thehose when the water is admitted into it. nor ends of the spokes I areclamped between the head J and the fiangerof the cam E, (see Fig. 4)suitable radial recesses being formed in the head or the flange, whichare secured together by bolts. The outer end of the spokes and the endsof the curved segments are halved onto each other, as represented at dg, and secured by bolts or rivets. An enlargement, f, on the spokes I,prevents the slats from being forced too far outward by the springs s.The ends of the slats are slot ted to fit the spokes, so that the slatscan move lengthwise of the spokes.

The valve D is attached to the supply-pipe O by the elbowl and nipple70, Fig. 4, or other suitable connection. The valve is preferably of thestraightway type, being arranged to be opened and closed by the lever F.The disks 0 are arranged to close against inclined seats in thevalve-shell-,the position when closed being indicated by the full linesin Fig. 3, and when opened, by the dotted lines 0'. m is a flanged capthrough which access is had to the disks and seats. The valve stem 1passes through a suitable stuffing box and is attached to the lower endof the lever F. The disks are provided with projecting arms, j, Fig. 3,so that as the lever swings from F to F, the disks are shifted from c too, and the valve opened. An arm a, pivoted to the lever F, by means ofthe pin 1) and extension piece K, carries at its lower end the roller L,which bears against the outer surface of the spiral cam E. The arm arests against the lever F, so that, as the cam revolves in the directionrepresented by the arrow in Figs. 2 and 3,'the lever is shifted from FtoF, thereby opening the valve and admit-ting water to the hose on thereel. The axis of the valve and its operating lever, as shown in Fig. 3,is cocentric to the axis of the cam and real and The inits position issuch that when the valve. is I closed the roller Lwill bear against{hntPor tion of tl "am n ar. at the cam center, but when the valve isopen and the lever at the extreme of its valve opening movement, theroller will be farthest from the cam center. The end of the lever servesas a handle for opening or closing the valve, and, when the cam isrevolved backward, the arm ct and roller L swing outward to the positionindicated at a L. By this construction the roller is prevented frominterfering with the reverse motion of the cam. It will also beunderstood that the first revolution of the reel and cam, opens thevalve fully by swinging the lover and roller to F L, and that, afterthese parts have arrived at this position, the cam can revolve as thehose is unwound further, without affecting the valve.

The pipe 7t, Fig. 4, is screwed into the inner end of: the valve shell,and the head revolves on it-,being supported by the standard G and cap0. The head is provided with a circular flange, '0, Fig. 4, whichsurrounds the pipe 71, and has at its outer end a flange 20, which turnsin a growe in the cap and in the standard (1- The interior surfaces ofthe cap and standard are made hexagonal, to fit. the inner end, as, Fig.4, of the valve D, and inside the end of the valve a circular recess isformed, which is filled with any suitable packing, 3 preferably apacking containing plumbago,which packing extends the full .ength of thepipe 71, as indicated at y, Fig. t,-the inner surface of the circularpart c Jeing formed of a Babbitt-metal sleeve, it desired. The innerside of the head is provided with the bend or elbow, e, to which thehose .3 is attached by the screw-connection o.

p is a boss on the elbow c, which receives he shaft 1, which extends tothe opposite .pider I1, and serves to hold the reel together. .he cap 0is provided with flanges and bolts iy which it is secured to thestandard, and he packing compressed so as to make the oint tight. Bythis construction, the metalto surfaces which revolve are kept out ofontactwith each other, so that they are preented from sticking t getherfrom rust.

The cap J is referably provided with a rojection or flange 0', Fig. 4,which engages ver the hexagonal end of the valve shell and ssists inholding the parts together. The 1p and standard prevent the valve fromlrning on the nipple 76.
